Erie is the cheapest insurance company, and arguably the most reliable insurance company as well. They score points by allowing customers to start their quote online, which we personally found to be a streamlined and fast process. Erie also scored the highest marks from the number of policies they offer. Erie offers pet coverage, free accident forgiveness, free vanishing deductibles, roadside assistance, and many more, essentially giving its customers a degree of flexibility not even found amongst the largest insurers. Customers of Erie may also be eligible for its Rate Lock program. This is a unique program where customers won't see their rates increase except for three reasons: you move to a different area, add or remove someone from your policy, or add or subtract a car. Lastly, despite its smaller size, Erie offers the same types of discounts larger national insurers provide such as bundling, anti-lock brakes, anti-theft, young driver and senior driver among others.
Making a claim with “the other driver’s” insurance company? That’s a third-party claim. Driving a company car and sustain an injury? You’re making a third-party claim there, too. Injured while driving your own car in the course of your job? A third-party claim with your employer’s insurance company would be your mechanism for recovery of medical and repair costs. Any claim made to an insurance company other than your own is considered a third-party claim.

While State Farm's shopping experience is well-reviewed, customers did not feel as strongly about it's claims handling process. The company scored about the same as the other four large companies, but was still mediocre. A large national company may be expected to not be very efficient because of the various departments involved in handling individual claims. If you want the assurances guaranteed to you by a large, "legacy" carrier, then State Farm is the best to go with.
Third-party claims are much more prevalent in “fault” states than in “no-fault” states. While no-fault generally require an injured party to first recover from their own insurance company, fault states have no such requirement. In fault states, if you sustain an injury to your person or damage to your vehicle in a car accident you can make a claim with “the other driver’s” insurance company -- provided they were at fault for the accident.

Comprehensive insurance is a coverage that helps pay to replace or repair your vehicle if it's stolen or damaged in an incident that's not a collision. Comprehensive typically covers damage from fire, vandalism or falling objects (like a tree or hail). If you're financing or leasing your car, your lender likely requires comprehensive coverage. If you own your vehicle outright, it's an optional coverage on your car insurance policy.
